제목 Synthesis and Photovoltaic Properties of Mesophorous TiO2for the Dye-Sensitized Solar Cell
초록 Dye-sensitized solar cell (DSSC) has attracted much attention due to their high performance and easy manufacturing process [1-3]. Photoinduced electron transfer between photosensitizers and colloidal wide band gap semiconductors such as TiO2 plays an important roll in DSSC cell [4-5]. The nanocrystalline titania is a most promising semi-conductor for DSSC electrode because the conduction band of titania is well optimized to inject electrons from the excited state of dye. To achieve high performance of DSSC, the titania electrode has the high crystalline anatase phase and surface area to increase the mobility of electron injected from dye LUMO and the amount of dye absorbed on the TiO2 surface, respectively. In this study we prepared the nanocrystalline mesoporous titania by the surfactant assisted templating method and the photovoltaic properties of DSSC based on TiO2 electrode synthesized with different temperatures was evaluated to optimize the cell performance.
